National Loop Co. 17' (2.5' X 6') Saw Cut Vehicle Detection Loop with 225' Lead-In for 8.5' Wide Driveways - P-NL8.5-18-225

Made for gate and access-control upgrades, the National Loop Co. 17' Saw Cut Vehicle Detection Loop with 225' Lead-In is an 18 AWG inductive loop, machine-wound and ready to seal into existing pavement. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. Installers saw a 1/8" by 1" deep slot into the existing surface, drop the prewound loop in, and seal the slot against moisture. Its 6' side spans the travel lane while the 2.5' side runs in the direction of traffic, leaving roughly 1' 3" of clearance on each edge, an arrangement well suited to older urban row homes, narrow driveways, and single-car gravel drives in rural areas.

Features:

• Precisely stacked wires let loop sealant fully encapsulate the loop for lasting weather protection
• Cuts down on faulty detection calls and repeat service trips thanks to consistent machine winding
• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced length of Polypropylene-insulated wire, leaving no splice point between the loop and lead-in to fail
• Predetermined number of machine-wound turns removes the guesswork of achieving optimal read range
